The basilar artery is the most important artery in the back of the brain. The basilar artery can develop a bulge that pushes outward, putting stress on the artery wall and causing it to burst. When basilar artery aneurysms burst, they account for an estimated 27 percent of ischemic strokes, according to neurologists affiliated with St. Louis University.
Brain aneurysm repair is a surgical procedure used to treat a bulging blood vessel in the brain that’s at risk of rupturing or tearing open. An aneurysm occurs when the wall of a blood vessel becomes thin and bulges or balloons out. Many aneurysms remain undetected because someone may not experience any symptoms until they rupture.
Tests to diagnose an abdominal aortic aneurysm include: Abdominal ultrasound. This is the most common test to diagnose abdominal aortic aneurysms. An abdominal ultrasound is a painless test that uses sound waves to show how blood flows through the structures in the belly area, including the aorta.
Results. Arteriovenous fistula aneurysms are defined by an expansion of the intimal, medial and adventitial layers of the vessel wall to a diameter of more than 18 mm. Treatment of arteriovenous fistula aneurysm is indicated if there is pain, risk of haemorrhage and flow disturbance (either low or high flow).
Arteriovenous fistula can be created in the antecubital fossa or arm area. Arteriovenous fistulae are prone to developing their own complications which include the formation of an aneurysm. Aneurysm formation may occur because of repeated punctures that can weaken the vein wall in some patients.

In general, an aneurysm is a weak spot in the wall of your access that can expand and eventually burst if not treated. In a true aneurysm, the artery or vessel dilates in response to the increased blood flow, sometimes causing a blood-filled sac to form.
A pseudoaneurysm happens as a result of injury to a blood vessel. The artery leaks blood, which then pools near the damaged spot. It's different from a true aneurysm, which happens when the wall of a blood vessel stretches and forms a bulge. Most pseudoaneurysms are complications from medical procedures.
An AV fistula is an abnormal connection between an artery and a vein, and is sometimes surgically created to help with haemodialysis treatment. In these cases, a shunt graft is inserted to aid the treatment. Unfortunately, sometimes the shunt will fail, known as graft malfunction.
a fistula, which is made by joining together an artery and vein to make a bigger high-flow blood vessel. a graft, in which a soft plastic tube is placed between an artery and a vein, creating an artificial high-flow blood vessel.
Abstract. Ischemic steal syndrome (ISS) is a complication that can occur after the construction of a vascular access for hemodialysis. It is characterized by ischemia of the hand caused by marked reduction or reversal of flow through the arterial segment distal to the arteriovenous fistula (AVF).
An AV fistula is a surgically placed "shunt"; that is, an artery is directly sutured to a vein. An artery is a high-pressure vessel that carries blood away from the heart and delivers nutrients and oxygen to the tissues.

An AV fistula is a connection, made by a vascular surgeon, of an artery to a vein. Arteries carry blood from the heart to the body, while veins carry blood from the body back to the heart. Vascular surgeons specialize in blood vessel surgery. The surgeon usually places an AV fistula in the forearm or upper arm.
Aneurysms are classified by location, etiology, or other characteristics. Pathological, blood-filled distension of blood vessel. Protruding sac in the wall of a vein, artery, or heart, frequently caused by microbial infection; may present as pain, pressure on nearby organs, or cardiac weakening.
Medicines and surgery are the two main treatments for aneurysms. Bulging or ballooning in an area of an artery secondary to arterial wall weakening. Pathological outpouching or sac-like dilatation in the wall of any blood vessel (arteries or veins) or the heart (heart aneurysm).
Most aneurysms occur in the aorta, the main artery traveling from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke. Aneurysms can develop and become large before causing any symptoms.
